FIRE AND WATER PROOF PAINT.

SPECIFICATIQN forming part of Letters Patent No. 326,776, dated September 22, 1885.

Application filed June 23, 1885. (N0 specimens.)

To all whom it may concern.-

Be it known that we, CHARLES H. PHIL- LIPS, J AMES TRODEN, and JOHN GOLLING, citizens of the United States, residing at Alpena, in the county of Alpeua and State of Michigan, have invented certain new and useful Improvements in Fire and lVater Proof Paint, of which the following is aspecification.

Our invent-ion relates to an improved paint compound especially adapted forv covering roofs, damp walls, or any surface where a fire and water proof paint is desirable.

Our paint consists of the following ingredients, combined in about the proportions set forth, namely: one barrel of tar, ten pounds red mineral, ten pounds keystone granite, ten pounds water-lime, eight pounds asbestus, ten pounds potash, and ten pounds alum.

The tarshould be boiled for about two hours, or until the gas has all escaped. The other components are then added to the tar, one at a time, in the order named, and while the latter is at the maximum heat, and the mixture boiled one hour, during which time it should be frequently stirred. It should be applied to wo0dshingles, for instancein its hottest conditionsay, while at a temperature of 220 Fahrenheit. In applying it to tin or iron surfaces the temperature may be 1esssay, 200 Fahrenheit.

The proportions herein named have been ascertained by careful experiment and are deemed to produce the best results; but said proportions may be varied somewhat without departing from the invention.

Made and applied as here described the paint produces a coating that will resist the ordinary action of both fire and water, and it is unaffected also by cold. It will not scale off.

Having described our invention, We claim and desire to secure by Letters Patent of the United States A paint compound consisting of tar, red mineral, keystone granite, lime, asbestus, potash, and alum, combined substantially in the proportions set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
